Figure 2 of a tile pattern has 8 tiles, while figure 5 has 14 tiles. If the tile pattern grows at a constant rate, how many tiles will figure 40 have?

Answer:
84 tiles
Step-by-step explanation:
Given that :
Figure 2 = 8 tiles
Figure 5 = 14 tiles
Growth rate :
(Figure 5 - figure 2)x= 14 - 8
3x = 6
x = 6/3
x = 2
(Figure 40 - figure 2) = 38 * x
Initial number of tiles + 38x
8 + 38(2)
8 + 76
= 84
Figure 40 = 84 tiles
